## Homework Statement

the centripetal acceleration of an object at Earth's equator results from the daily rotation of Earth. Calculate the object's centripetal acceleration, given that the radius of Earth at the equator is 6.38*10^6m.

## Homework Equations

a=v^2/r

## The Attempt at a Solution

I really have no idea how to solve this question, how can I calculate the centripetal acceleration with only the radius?
